Penn ar Roz, un assemblage lithique de la transition Pléistocène-Holocène à Châteaulin (Finistère)

Abstract : A CRM excavation of the Penn ar Roz site in Châteaulin in Finistère (Brittany, France) by INRAP allowed the discovery of various archaeological records attributed to a wide chronology. A lithic assemblage attributed to the Pleistocene-Holocene transition was identified among Iron Age and medieval artifacts collected on this 34000 m2 site located on a plateau above a large meander of the Aulne River. The assemblage is technologically homogeneous despite an important dispersal of the artifacts and obvious taphonomic issues. The various technical characteristic highlighted by our study suggest this assemblage to be the result of an installation of post-azilian communities at the very end of the Upper Paleolithic durind the GS1 (Younger Dryas)-Holocene transition. This discovery adds new evidence for the understanding of this key period in Western France. It brings new information about the situation of the western extremity of the Armorican peninsula during this period and asks the question of adaptation of these very demanding lithic productions in a raw materials scarcity context.
